Hey guys, sorry to give you a screenshot of the picture comparison but I'm a bit lazy today and forgot to turn off the geo-location tags. Hopefully i get some more shots in later this weekend and post back later.
I'm using the v1.4 the original GCAM app from the XDA article. I can't say that I trust the v2.2 from the Russian site at the moment so sorry again. If it gets updated and the XDA article says it was updated I'll be more willing to try the v2.2 app.
What you see is the Essential app on the left versus the GCAM app on the right. I prefer what I've seen from the Essential app but in actual usage the GCAM works much faster and believe it or not feels more stable. As you can see there is definitely a difference in picture quality especially around the glass and text. Mind you I'm coming from a Pixel XL so that is my frame of reference as far as what I should be expecting from both apps. From looking at the picture versus what my eye is seeing the GCAM is more true to my eye, however I find the light/dark balance more pleasing on the Essential app. Personally I really hope Essential gets it together because from what I've read the GCAM software doesn't make use of the monochromatic lens and I think that if someone can combine the best function of both apps we as the users would be the real winners.
If I can get more shots without the metadata in it I'll be sure to post them up. Otherwise I'm subscribed to this thread so I can keep up with the latest updates for the GCAM app.
